The children won’t sleep – Paul and Ally thought these nights were over. Paul spends the night fighting his own anger and his children’s inability to go the f**k to sleep.

Luke's parents and the surprising arrival of Ally's estranged father cause Paul and Ally to scrutinize their hopes and dreams for Luke and Ava and discover how far they will go for the sake of their kids.

Ally attempts to acclimatize to Michael's continued presence while Paul begins to question if his accident-prone son's frequent injuries might actually be his fault.

In the wake of Michael’s death, the family stay with Darren at his country house, but Paul’s attempt to give Ally space by taking on kid duties and Darren’s fixation on work doesn’t help Ally find a chance to say goodbye.

It’s half term and Luke is responsible for taking Lenny the class bear on an adventure. Lenny has been to Italy, Peru and beyond, but Paul can’t even manage to get the family and the godforsaken bear out of the house to the local park.

Family life is thrown off kilter as Ally spends her weekdays in Berlin and weekends in London. Paul, Luke and Ava try to muddle through without her, but the children aren’t sleeping again and it takes its toll on Paul.

Luke’s condition worsens and he is admitted to a specialist pediatric unit. As Paul, Ally and their parents desperately wait for news, stress and fear cause cracks to form within the family.

The kids are growing up fast – Ava is now 10 and Luke is about to turn 13. With their burgeoning independence comes the question of whether Paul and Ally’s parenting style still works. Clue: no.

Paul fears his culturally fragmented family has lost a vital connection. Gentrification impacts Jim and Jackie as the last of their old neighbours move out and more young professionals move in.

A sudden death impacts the older generation of the Worsley family. Ava struggles to keep a profound secret from Paul. Ally finds it difficult to hide her true feelings from Luke.

It’s five years since we last saw the Worsleys, with Paul and Ally on the verge of splitting, and Jim and Jackie in turmoil. Things are no less dramatic now as Luke and girlfriend Maya drop a bombshell at Christmas dinner that will change everyone’s lives forever.

The reality of Luke’s announcement hits, and Paul and Ally worry about the decision he and Maya have made and whether they should support them. As a New Year starts, the Worsley family gather together with Maya’s family, united in their love and worry.

Paul and Ally find themselves parenting Jim and Jackie as well as a conflicted Luke. Ava and Holly get closer and Ava decides to take a risk, while Paul meets an old friend and realizes that he might, after all, be happy.

As Paul and Ally try to help Luke, struggling with being both a dad and a student, they find they have very different ideas about the best way forward. Jackie’s condition is becoming more noticeable, and Jim is determined to help out.

Jackie’s health is continuing to worsen. Paul helps out a distressed Luke but finds himself in more conflict with Ally. At Baby Jay’s naming party, Ava declares her love, and Paul makes an offer that will take him and Ally back in time.
